Glsl texturesize performance. What can I do to imp.

Glsl texturesize performance. When having all first attributes stored close to each other, chances are high that parallel shaders read neighboring texels which will be faster. I use glsl and opengl 4. The components in the return value are filled in, in order, with the width, height and depth of the texture. This is the shader: void main() . 0" encoding="UTF-8" standalone="no"?> Another option is to use textureSize function. with shader A I get 20fps, with shader B I get 40fps on average. In order for the GPU to work with textures through samplers, the driver needs to know the textures dimensions, and a good implementation will be able to access those dimension much more easily/quickly then passing them around in buffers or as push constants. With a shared layout GLSL is allowed to reposition the uniform variables for optimization as long as the variables' order remains intact. Mar 24, 2023 · It’s hard for me to imagine a use-case for a non-postprocessing / non-raymarching shader, in which you’d need to sample a texture 100-1000 times per pixel.
